B - IR (or wired) printer output

C - Display data output (to drive the angled display)

Item C seems the most challenging (I suspect that isn't available now).

All three of these could be done if the DM42 could act as a USB Host. That possibility would depend on the capability of the SoC chosen for the calculator. If limited to the role of USB device, the DM42 could present itself as an HID to a controller embedded in the desktop case.

Addendum: Or just extend the serial console to accept commands to redirect printer output and display state to the serial output.
